Reproduction steps

msw version: 2.2.1

For some reason, the request object here is occasionally undefined. When it is, this line throws

Cannot read properties of undefined (reading 'url')

Seem to be introduced during 0e9d65f

I don't know if this is intentional or not, or what the fix is, just reporting this runtime error. Thanks for all you do!

Current behavior

Throws

Cannot read properties of undefined (reading 'url')

Expected behavior

Does not throw this error

I've been experiencing this as well for a couple of weeks on a project, came here to see if anyone else had opened a bug. It looks like its also been raised here #2053 and the last comment there is that its being looked into and downgrading to 2.1.4 in the meantime is one workaround (in case that helps).

[kmiwa-clari]

Yup that's what I ended up doing although I think 2.1.7 should work as it's just before the 2.2.0 release which added this runtime error.

Opened a fix in #2094.

Also marking this as a duplicate of #2053.

@mbwestphal, I believe the open issue #2146 is about the same problem.
